*corosync* is hanging? or rather *pacemaker*, maybe? > Is this normal behavior ? Is there a parameter to prevent this ? > IMHO a unmanged resource should not prevent corosync from stopping. It may be expected behaviour. Would this maybe explain what you see: http://bugs.clusterlabs.org/show_bug.cgi?id=5028#c12 | Andrew Beekhof 2012-03-07 02:42:08 CET | | A related patch has been committed upstream: | https://github.com/beekhof/pacemaker/commit/8d2f237 | | with subject: | | High: PE: Bug cl#5028 - Unmanaged services should block shutdown unless in | maintainence mode | | Further details (if any): | | 'Unmanaged' in this context means failed with on-fail=block.
